1, sweating is the product of body temperature regulation and metabolism! If you sit still, you will sweat when the temperature is high, so this is human body temperature control.
2. Fat can't be consumed in the first 30 minutes of aerobic exercise, and the energy supply of human body is staged. So the coach will say to jog for at least 30 minutes, even 1 hour. After 30 minutes of aerobic treatment, fat burning began to increase.
To sum up, water loss is much greater than fat burning. So it's useless to lose weight by TV advertising!
Supplement: I said above, don't trust drugs. Oxygen alone will make you very shapeless. If you can go to the gym, you need to combine dumbbells, barbells and equipment to achieve your goal. thank you
